Continuous Improvement on Carbon Emissions:

1. In order to respond to the nationa1 ca11， cope with climate change, and achieve sustainable development, WTOO has set carbon emissions targets

specifically and continuously strives to reduce carbon emissions. At the same time, we use GHG standards to conduct statistica1 management on carbon

emissions of our company.

2. Based on the existing carbon emissions, and the amount of organic fuel used to measure the emissions of exhaust gases, WTOO plans to reduce carbon emissions by means of equipment optimization, energy replacement, etc. What is more, we plan to reduce carbon emissions by 25% by 2025 and 50% by 2030， continue to make internal improvements, and reduce carbon emissions, so as to contribute to the fight against g1oba1 climate change and green development.
